Although some of these methods are rather simplistic, the final outcome of the prosthesis depends on the artistic skill of the maxillofacial prosthetist, especially in sculpting and orienting the wax pattern
Aim of the study is to highlight changes and dimensional accuracy of wax patterns
and castings are measured weekly to make sure the process is not drifting;
Among four robotic cells, a single Signicast employee makes her rounds, welding the wax patterns
onto an investment tree before hanging them in the automated storage/retrieval system, which transports the trees through the remaining operations.
When formulated into a resin to replace polymer resins or wax patterns
, it drastically reduces the amount of time required to produce an investment casting by eliminating the 8-12 hour long burn-out cycle.
Others had kaki glaze with wax patterns
, white slip with iron and cobalt decoration or hakeme with copper splashes.
Use a wax crayon to draw patterns on a dry egg.
For example, the ADL can use the laboratory 3M ESPE Lava CAD/ CAM system (Figure 3) to fabricate wax patterns
from the digital impression, cast the gold crown, and perform final seating/occlusion adjustments on the articulated SLA casts.
Beech Aerospace Systems manufactures tooling dies and wax patterns
used to create cast parts primarily for the aerospace industry.
GSC used stereolithography to produce wax patterns
from the CAD model then cast the prototype part in CF-3 stainless steel.
Ms Williams adds: "If we were to create wax patterns
with such a high level of detail, they would be too fragile to ship to our casting contractors.
The printer will be offered as a solution for producing castable wax patterns
directly from a variety of computer-aided design (CAD) software applications.
